28 // One can fetch any of the data objects with all the calls to runloader, muon loader and AliMUONData
29 // done behind the scenes and automatically.
30 // This interface in not necessarily the fastest way to fetch the data but it is the easiest.
31 // Note: If independant calls to the run loader, muon loader or AliMUONData objects are interspersed
32 // with calls to the AliMUONDataInterface to fetch data, one might need to call the Reset method
33 // between these method calls at some point to prevent AliMUONDataInterface from getting confused.
34 // This is necessary since this object assumes the state of runloader, muon loader nor AliMUONData
35 // has not changed between calls. If the state has changes then one must call Reset so that
36 // AliMUONDataInterface refreshes what it knows about the state of the loader and AliMUONData objects.
